Theoretical studies on the structural and optical properties of a series of Os(II) diimine complexes [Os(NN)(CO)2I2] (NN=2,2prime-bipyridine(bpy), 4,4prime-di-tert-butyl-2,2prime-bipyridine(dbubpy), 4,4prime-dichlorine-2,2prime-bipyridine(dclbpy)) ...
In the presence of excess Cu(2+), phenothiazine moiety is oxidized to a stable entity which is incapable of electron donation to the MLCT excited state of Ru(bpy)(3)(2+). The emission of the Ru(bpy)(3)(2+) moiety is thus re...
